Execute cardiac MRI protocols including patient screening, gating setup, contrast administration, multiplanar localization, cine imaging, late gadolinium enhancement, T1/T2 mapping, and post-processing to produce diagnostic-quality datasets.
Perform cardiac CT angiography (CTA) studies, including coronary CTA, calcium scoring, and structural heart CT protocols, managing dose optimization, contrast injection protocols, and ECG-gating to minimize artifacts and radiation exposure.
Operate nuclear cardiology equipment and complete SPECT and PET myocardial perfusion imaging, including pharmacologic and exercise stress protocols, tracer dosing, attenuation correction, and reconstruction to generate accurate perfusion and viability studies.
Prepare patients for cardiac imaging procedures by obtaining relevant histories, assessing contraindications (e.g., renal function, implantable devices), explaining procedures, and ensuring patient safety and comfort throughout the exam.
Administer intravenous contrast agents and radiopharmaceuticals per institutional policy, calculate appropriate dosages, monitor for adverse reactions, and document administration following safety and regulatory requirements.
Acquire, review, and optimize raw imaging data in real time, repeating or modifying views and parameters as needed to ensure diagnostic completeness and avoiding artifacts that could compromise interpretation.
Perform standardized quantitative measurements (e.g., ejection fraction, LV volumes, valve gradients, coronary calcium score) and preliminary calculations that support cardiologist interpretation and clinical decision-making.
Post-process images using PACS, dedicated vendor software (GE, Philips, Siemens), and advanced analysis tools (3D/4D reconstruction, strain imaging, perfusion quantification) to produce final study packages and measurement reports.
Communicate findings, exam quality, and pertinent clinical observations to interpreting physicians in a clear, timely manner and escalate urgent or unexpected abnormal results per institutional protocols.
Maintain strict adherence to radiation safety, infection control, and contrast safety protocols, including ALARA principles, lead shielding, hand hygiene, and documentation of allergies/consent.
Lead and participate in regular quality assurance and quality improvement initiatives, including equipment performance checks, phantom testing, peer review of image quality, and protocol standardization to improve diagnostic yield.
Troubleshoot imaging equipment issues, liaise with biomedical engineering and vendor service teams for preventive maintenance and repairs, and document equipment downtime and corrective actions.
Coordinate scheduling and workflow for cardiac imaging clinics, stress labs, and interventional procedures to optimize throughput, minimize patient wait times, and ensure efficient use of resources.
Supervise and mentor junior technologists, sonography students, and cross-trained staff, providing hands-on instruction in imaging protocols, patient positioning, and safety best practices.
Support multidisciplinary care conferences (heart team meetings, structural heart rounds, tumor boards) by preparing and presenting images, measurements, and key findings to support patient care planning.
Ensure all imaging documentation, procedural consents, and billing information are accurately completed in the electronic health record (EHR) and PACS to support compliance and reimbursement.
Contribute to protocol development and optimization for emerging cardiac imaging techniques such as 3D echocardiography, strain imaging, CT fractional flow reserve (CT-FFR), and PET viability testing.
Participate in research studies, clinical trials, or registry data collection by following research imaging protocols, maintaining source documentation, and supporting investigators with standardized imaging acquisition and analysis.
Provide emergency imaging support for acutely ill cardiac patients, including rapid bedside transthoracic echo, focused cardiac ultrasound (FOCUS), and imaging for perioperative or critical care cardiology needs.

Secondary Functions

Support departmental data collection and analytics efforts related to exam volumes, exam turnaround times, dose metrics, and quality indicators to inform continuous improvement.
Collaborate with IT/PACS teams to optimize DICOM tagging, study naming conventions, and workflow automation for efficient retrieval and AI tool integration.
Participate in cross-functional initiatives to integrate cardiac imaging data into population health and value-based care programs by standardizing metrics and reporting.
Assist in the development and delivery of continuing education sessions, competency assessments, and credentialing documentation for cardiac imaging staff.
Act as a clinical liaison with vendor partners during software upgrades, new modality rollouts, and acceptance testing to validate cardiac-specific imaging workflows.
Evaluate and recommend imaging consumables, contrast agents, and accessory devices to ensure cost-effective and clinically appropriate supplies.
Support inventory control and ordering processes for cardiac imaging supplies, contrast media, and radioactive tracers within compliance guidelines.
Provide patient education materials and discharge instructions related to imaging follow-up, contrast precautions, and scheduling for additional tests when indicated.
